MagAO Imaging of Long-period Objects (MILO). I. A Benchmark M Dwarf Companion Exciting a Massive Planet around the Sun-like Star HD 7449
Timothy J. Rodigas, Pamela Arriagada, Jackie Faherty +17
We present high-contrast Magellan adaptive optics (MagAO) images of HD 7449, a Sun-like star with one planet and a long-term radial velocity (RV) trend. We unambiguously detect the…
The LEECH Exoplanet Imaging Survey: Characterization of the Coldest Directly Imaged Exoplanet, GJ 504 b, and Evidence for Super-Stellar Metallicity
Andrew J. Skemer, Caroline V. Morley, Neil T. Zimmerman +39
As gas giant planets and brown dwarfs radiate away the residual heat from their formation, they cool through a spectral type transition from L to T, which encompasses the dissipati…
Accreting Protoplanets in the LkCa 15 Transition Disk
S. Sallum, K. B. Follette, J. A. Eisner +14
Exoplanet detections have revolutionized astronomy, offering new insights into solar system architecture and planet demographics. While nearly 1900 exoplanets have now been discove…
Magellan Adaptive Optics first-light observations of the exoplanet beta Pic b. II. 3-5 micron direct imaging with MagAO+Clio, and the empirical bolometric luminosity of a self-luminous giant planet
Katie M. Morzinski, Jared R. Males, Andy J. Skemer +14
Young giant exoplanets are a unique laboratory for understanding cool, low-gravity atmospheres. A quintessential example is the massive extrasolar planet Pic b, which is 9 AU f…
Orbital Differential Imaging: A New High-Contrast Post-Processing Technique For Direct Imaging of Exoplanets
Jared R. Males, Ruslan Belikov, Eduardo Bendek
Current post-processing techniques in high contrast imaging depend on some source of diversity between the exoplanet signal and the residual star light at that location. The two ma…
Direct Exoplanet Detection with Binary Differential Imaging
Timothy J. Rodigas, Alycia Weinberger, Eric E. Mamajek +5
Binaries are typically excluded from direct imaging exoplanet surveys. However, the recent findings of Kepler and radial velocity programs show that planets can and do form in bina…
The Subaru Coronagraphic Extreme Adaptive Optics system: enabling high-contrast imaging on solar-system scales
N. Jovanovic, F. Martinache, O. Guyon +35
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a multipurpose high-contrast imaging platform designed for the discovery and detailed characterization of ex…
New Extinction and Mass Estimates of the Low-mass Companion 1RXS 1609 B with the Magellan AO System: Evidence of an Inclined Dust Disk
Ya-Lin Wu, Laird M. Close, Jared R. Males +9
We used the Magellan adaptive optics system to image the 11 Myr substellar companion 1RXS 1609 B at the bluest wavelengths to date (z' and Ys). Comparison with synthetic spectra yi…
Multiwavelength Observations of NaSt1 (WR 122): Equatorial Mass Loss and X-rays from an Interacting Wolf-Rayet Binary
Jon C. Mauerhan, Nathan Smith, Schuyler D. Van Dyk +5
NaSt1 (aka Wolf-Rayet 122) is a peculiar emission-line star embedded in an extended nebula of [N II] emission with a compact dusty core. This object was characterized by Crowther &…
First-light LBT nulling interferometric observations: warm exozodiacal dust resolved within a few AU of eta Corvi
D. Defrère, P. M. Hinz, A. J. Skemer +37
We report on the first nulling interferometric observations with the Large Binocular Telescope Interferometer (LBTI), resolving the N' band (9.81 - 12.41 um) emission around the ne…
New Spatially Resolved Observations of the T Cha Transition Disk and Constraints on the Previously Claimed Substellar Companion
S. Sallum, J. A. Eisner, Laird M. Close +11
We present multi-epoch non-redundant masking observations of the T Cha transition disk, taken at the VLT and Magellan in H, Ks, and L' bands. T Cha is one of a small number of tran…
New Extinction and Mass Estimates from Optical Photometry of the Very Low Mass Brown Dwarf Companion CT Chamaeleontis B with the Magellan AO System
Ya-Lin Wu, Laird M. Close, Jared R. Males +9
We used the Magellan adaptive optics (MagAO) system and its VisAO CCD camera to image the young low mass brown dwarf companion CT Chamaeleontis B for the first time at visible wave…
